Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICABILITY The present invention relates to a reset device for multiple linked switches.

Conventional Technology First, a conventional example is shown in FIGS. 4 (a) (b) (c). A plurality of sliding operation bodies 1, 2 and 3 are slidably provided by being urged in one direction by a spring 4. These sliding operation bodies 1,
Knobs 5 are formed on the upper end surfaces of 2 and 3, and protrusions 6 are formed on the side surfaces.
Are formed. In addition, the sliding operation body 1,
These sliding operation bodies 1, 2, 3 facing the lower surfaces of 2, 3
Is formed with a receiving portion 8 that restricts the sliding range. Further, the slider 9 facing the end of the protrusion 6 on the opposite side of the knob 5 is urged by the spring 10 in one direction orthogonal to the sliding direction of the sliding operation bodies 1, 2, 3 and the stopper 1
The sliding range is regulated by 1 so as to be slidable. Locking edges 13 and 14 that engage with the side surface 12 of the protrusion 6 are formed on the slider 9, and the locking edges are generated when the sliding operation bodies 1, 2 and 3 are slid against the biasing force thereof. An inclined portion 15 is formed on the side surface 12 of the protrusion 6 so as to incline in a direction in which a component force for pressing the slider 13 or 14 against the biasing force of the slider 9 is generated. The locking edge 13 is the slider 9
The other engaging edge 14 is formed at one edge of the opening 16 formed at the intermediate portion of the slider 9. The sliding operation body 1 is for resetting and does not have a contact, but the other sliding operation bodies 2 and 3 have a contact (not shown) that is brought into contact with and separated from a fixed contact (not shown). There is something.

Next, the operation will be described. When the sliding operation piece 2 or 3 is pressed in the state of FIG. 4 (a), the slanted portion 15 of the projection 6 and the locking edge 14 come into contact with each other, and the slider 9 causes the spring 10 to move by the component force generated from this contacting force. The slider 9 returns to the left by the urging force of the spring 10 when the protrusion 6 passes under the locking edge 14 by sliding to the right against the force of
As shown in FIG. 3B, the upper surface of the protrusion 6 is pressed to resist the force of the spring 4 and the sliding operation piece 2 is maintained in the pressed state. As a result, circuit switching is performed.

As described above, the sliding operation bodies 2 and 3 having the contacts are operated for the switching operation, and since the slider 9 is slid to the right once during the pushing operation, other sliding operations are performed before that. If the dynamic operating body 3 or 2 has been pushed, the sliding operating body 3 or 2 is returned upward, and the slider 9 which is returned is kept in the pushed state.

Further, when all the sliding operation bodies 2 and 3 for switching are returned to the upper side, as shown in FIG. 4 (c), the sliding operation body 1 dedicated to the reset is pushed in and the inclined portion 15 of the projection 6a is pushed. The slider 9 is pushed to the right by the
Return to above. The sliding operation body 1 needs to be returned by the urging force of the spring 4 by removing the external force from the knob 5, and therefore, the sliding operation body 1 for resetting has another function to prevent the returning operation of the slider 9. Sliding operation body 2,
3 has a protrusion 6a longer than the protrusion 6.

SUMMARY OF THE INVENTION However, the above-mentioned problems are associated with the protrusion 6 of the sliding operation bodies 2 and 3 for switching and the protrusion 6 of the sliding operation body 1 for resetting.
Unlike a, parts cannot be commonly used, which is inconvenient in production management.

Therefore, as shown in FIG. 5, the slider 9
By forming a crank-shaped bent portion 21 at one end of the and the locking edge 13 at the end edge of the bent portion 21, the shape dimensions of the projections 6 of all the sliding operation bodies 1, 2, 3 can be changed. Equalize,
In the case where the sliding operation body 1 for exclusive use with the reset is pressed, the returning operation of the slider 9 is blocked by the side surface of the protrusion 6 and the operation is performed by the force of the spring 4 when the external force is removed from the knob 5. is there. Such a device is actually developed in 60-60.
As described in Japanese Patent No. 243, however, the one shown in FIG. 5 shows that the bending portion 21 of the sliding operation bodies 2 and 3 for switching does not contact the slider 9 until the projection 6 abuts on the slider 9. The distance until the projection 6 of the sliding operation body 1 for reset contacts the slider 9 is increased by the offset amount h. That is, the depth of the blank push becomes deep and the feeling of operation becomes completely different.

Means for Solving the Problems A plurality of sliding operation bodies for holding contacts and a sliding operation body for reset are arranged in parallel and are urged in one direction to be slidably provided. A protrusion is formed on the side surface of the slider, and the slider for holding the sliding operation body except for the sliding operation body for resetting is pushed in one direction along the arrangement direction of the sliding operation body. Along with the stopper, the sliding range is regulated so as to be slidable, and the slider is formed with a plurality of locking edges that engage with the side surface of the protrusion, and the sliding operation body is resisted against its biasing force. At least one of the side surface of the protrusion and the locking edge that come into contact with each other when slid is formed with an inclined portion that is inclined in a direction that generates a component force that presses the slider against its urging force. The contact that touches the side surface of the protrusion of the sliding operation body for resetting. An extension is formed at the edge along the sliding direction of the sliding operation body.

Therefore, when the sliding operation body is slid against the urging force of the sliding operation body, the side surface of the protrusion abuts the engaging edge of the slider, and the slider is slid by the component force generated from the abutting force. , The sliding operation bodies other than the sliding operation body being pressed are reset. Further, since the extension portion is formed on the locking edge that abuts the protrusion of the sliding operation body for reset, the protrusion of the sliding operation body for reset is not Even if the lengths are set to the same length, the sliding operation body can be restored when the pressing force is removed from the reset sliding operation body.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 (a) (b) (c). The same parts as those described in FIGS. 4 (a) (b) (c) and FIG. 5 are designated by the same reference numerals and the description thereof will be omitted. One locking edge 13 that contacts the side surface 12 of the protrusion 6 of one sliding operation body 1 specified for resetting is along the sliding direction against the biasing force of the sliding operation body 1. The extension portion 17 is formed.

In such a configuration, when the sliding operation piece 2 or 3 is pressed in the state of FIG. 1 (a), the slider 9 is converted into the force of the spring 10 by the component force generated from the contact force between the protrusion 6 and the inclined portion 15. When the protrusion 6 is pushed to the right against it and the protrusion 6 passes under the locking edge 14, the slider 9 is returned to the left by the urging force of the spring 10, and as shown in FIG. 1 (b), The upper surface of the protrusion 6 is pressed to resist the force of the spring 4, and the sliding operation piece 2 is maintained in the pressed state.

When all the sliding operation bodies 2 and 3 dedicated to switching are returned upward, as shown in FIG. 1 (c), the sliding operation body 1 for resetting is pushed in and the slanted portion 15 of the projection 6 is depressed. The slider 9 is pressed to the right by and the sliding operation bodies 2 and 3 are returned upward during this period. In this case, the sliding operation body 1 for reset has a short projection 6 like the projection 6 of the sliding operation bodies 2, 3 for switching, but the extension 17 following the locking edge 13 is The protrusion 6 presses and prevents the slider 9 from returning. As a result, the sliding operation body 1 is returned by the biasing force of the spring 4 when the pressing force is removed from the knob 5. Therefore, the sliding operation bodies 1, 2 and 3 can be commonly used by making all the projections 6 equal in shape and size.

Although the protrusion 6 has a bilaterally symmetrical shape, as shown in FIG. 2, the inclined portion 15 is provided only on one side in contact with the locking edges 13 and 14.
May be formed. Further, as shown in FIG. 3, a protrusion 19 having a side surface 18 parallel to the sliding direction of the sliding operation bodies 1, 2 and 3 is formed on the sliding operation bodies 1, 2 and 3, and the slider 9 is formed.
Even if the slanted portion 20 is formed on the engaging edges 13 and 14 of the slider 9 and the slider 9 is slid by a component force based on the contact force between the protrusion 19 and the engaging edge 13 or 14, the same purpose is achieved. be able to.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, when the sliding operation body is slid against the urging force of the sliding operation body, the component force generated from the contact force between the side surface of the protrusion and the locking edge of the slider is generated. The slider can be slid by and the sliding operation body other than the sliding operation body that is being pressed can be returned, and an extension portion is provided at the locking edge that abuts the protrusion of the reset sliding operation body. Because it is formed
Even if the protrusion of the reset sliding operation unit is set to the same length as the protrusions of other sliding operation units, this sliding operation unit will be removed when the pressing force is removed from the reset sliding operation unit. It is possible to return, so that it is possible to use a common sliding operation body in which the projections have the same size and shape, which reduces the number of parts and rationalizes production control. Have.
